Abstract
Abstract An electrical connector for reliably and electrically connecting a daughter board and a mother board, includes a first insulative housing, a second insulative housing for electrically receiving the daughter board, and a pair of board locking devices. Each board locking device includes a first operative portion for providing a user with a manually locking operation, a protrusion for locking a corresponding notch of the inserted daughter board, and a moveable pin having a second operative portion for providing the user with a manually releasing operation. The moveable pin of the board locking device can be restricted within and linearly slide along a pair of L-shaped slots of the first housing whereby the user can selectively lock or release the daughter board. An elastic supporting portion is adapted to maintain a locking/releasing position of the board locking device with respect to the inserted daughter board under a stable and reliable situation.
